The eruptive xanthoma associated with primary hyperlipidemic states is the cutaneous manifestation of the elevation of the triglyceride fraction. This elevation is due to the inability to handle either excessive fat or carbohydrate intake. Understandably, dietary therapy is effective in the control of hypertriglyceridemia.
Two patients are presented with eruptive xanthoma with an associated elevation of the serum triglycerides. Both of these patients were found to have a carbohydrate-induced state which responded rapidly to dietary therapy.
